Solidity: Fails to compile with -o output dir option if compiled file is in a different then current directory

[marekkirejczyk]

For following command:
solc --abi -o '/tmp' './spec/fixtures/greeter.sol'

You get following messages:

Exception during output generation: /tmp/solidity-20170201-68591-whagys/solidity_0.4.9/solc/CommandLineInterface.cpp(469): Throw in function void dev::solidity::CommandLineInterface::createFile(const string &, const string &)
Dynamic exception type: boost::exception_detail::clone_impl<dev::FileError>
std::exception::what: FileError
[dev::tag_comment*] = Could not write to file: /tmp/./spec/fixtures/greeter.sol:greeter.abi

The source filename is concatenated with destination folder with source pathname.

So instead of:
./spec/fixtures/greeter.sol:greeter.abi
we got:
/tmp/./spec/fixtures/greeter.sol:greeter.abi

It does work if you use solc --abi -o /tmp spec/fixtures/greeter.sol does it?

[marekkirejczyk]

Nope, error message is:

Exception during output generation: /tmp/solidity-20170202-25074-udp7o6/solidity_0.4.9/solc/CommandLineInterface.cpp(469): Throw in function void dev::solidity::CommandLineInterface::createFile(const string &, const string &)
Dynamic exception type: boost::exception_detail::clone_impl<dev::FileError>
std::exception::what: FileError
[dev::tag_comment*] = Could not write to file: /tmp/spec/fixtures/greeter.sol:greeter.abi

It does work if I navigate to spec/fixtures and type:

solc --abi -o /tmp greeter.sol

@marekkirejczyk I think you are using MacOS and this is actually the same problem as #1631. For me on Mac #1648 fixes this.

[axic]

I think fixed by #1648. Please reopen if persists (see nightly tomorrow or the next release).

Happenned to me today:

PS C:\Users\Alex\source\repos\Solidity24\Solidity24> solc "Example.sol" -o "obj/Debug/" --bin --abi --overwrite

    function mortal() public {
        owner = msg.sender;
    }

    /* Function to recover the funds on the contract */
    function kill() public {

            selfdestruct(owner);
        }
    }

contract greeter is mortal {
    /* Define variable greeting of the type string */
    string greeting;

    /* This runs when the contract is executed */
    function greeter(string _greeting) public {
        greeting = _greeting;
    }

    function greet() public constant returns (string) {
        return greeting;
    }
}

I found out what happens: it fails when path ends with separator. obj/debug works while obj/debug/ doesn't.
